Paper Abstract

This paper presents a novel approach to generate object-adapted fringe, which based on scattered data interpolation. It can effectively solve the problems of the existing methods, such as complicated computation process and low accuracy. It needn't map the projector pixels coordinate onto the camera coordinate, only map the camera pixels coordinate onto projector coordinate. The phase of integer pixels of projector coordinate can be interpolated in the term of phase distribution of wanted fringe pattern. Compared to the presently algorithms, the advantages of this algorithm are simple and highly efficiency. This paper expatiates on the principle of the object-adapted fringe generation method using scattered data points. Simulation analysis and experiment results prove the validity and feasibility of the new approach. We also have compared the result between this new approach and other existing methods.
